Although wireless sensor networks (WSNs) have been utilized for over one decade, it is now heavily used by many modern applications such as medical observance, disaster management and environmental monitoring. This type of network suffers from limited energy and a short lifetime in addition to the low channel bandwidth. Bandwidth represents the major challenges of such systems due to the great impact of communication cost on the consumption of nodes power. Clustering has been proven to be one of the best techniques to conserve the energy of WSNs. LEACH (low energy adaptive clustering hierarchy) protocol is one of the most fundamental works of WSN clustering. However, this protocol suffers from some drawbacks, especially in the setup phase where CH is selected randomly. This work aims to enhance LEACH by identifying a cluster head according to the lowest degree of consuming energy. The results clarify the ability of this work to enhance LEACH while prolonging the lifetime and improving the performance of WSN.

尽管无线传感器网络 (WSN) 已经使用了十多年，但它现在被许多现代应用大量使用，例如医学观察、灾害管理和环境监测。除了低信道带宽之外，这种类型的网络还受到能量有限和寿命短的影响。由于通信成本对节点功率消耗的巨大影响，带宽代表了此类系统的主要挑战。集群已被证明是保存 WSN 能量的最佳技术之一。LEACH（低能量自适应聚类层次）协议是 WSN 聚类最基本的工作之一。然而，该协议存在一些缺点，特别是在随机选择 CH 的设置阶段。这项工作旨在通过根据最低能耗程度识别簇头来增强 LEACH。结果阐明了这项工作在提高 LEACH 的同时延长寿命和提高 WSN 性能的能力。
